ABSTRACT:
In an apparatus for supplying powder to a continuous casting mold, which has a powder hopper, a pneumatic powder-conveyor connected with the bottom portion of the powder hopper and a powder supplying nozzle connected with the pneumatic powder-conveyor, a heating and heat-retaining device and a gas injection device are mounted on the side wall of the powder hopper.
The heating and heat-retaining device is intended for maintaining the temperature of powder in the powder hopper within a required range, so as to keep its fluidity at a desired level, thereby preventing build-up of powder on the side wall of the powder hopper and its densification. The gas injection device is to inject dry gas into the powder hopper, so as to cause powder to flow down smoothly along the surface of the inside wall of the powder hopper.
